1') all whom it may concern:

Be it known that .l, WILLiAu R. M.I LLER, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of .lennsylvania, have invented certain new and useful improvements in Feeding Apparatus for (.ias-iroducers, of which the following is a specilication, reference being had therein to the accompanying drawing,

forming part of the specification, in which- Figure l.is a vertical sectional view of a gas produce-r provided with my improved feeding apparatus. Fig. 2. is a similar view of the upper portion of the structure showing Fig. -23. is a detail side view of the actuating cam mech anism. Fig. i. is a horizontal sectional view on the line i\". i.\". of Fig. 2. Fig. is a similar view on the line V. V. of Fig. 2.

2O Fig.6. is an enlarged detail view of the hop .per door-actuating eam.

My invention refers to improvements in the class of feeding mechanism for gas producers, furnaces, or similar structures wherein it is desirable to charge measured quan titit-s of fuel or other material into the furnace chamber periodically from time to time, and the objects in view are to provide an actuating mechanism for the diiiereut opene. valves, gates, hell, etc. so that the measured charges of fuel may be droppi d from time to time from the storage hopper or bin upon supporting gates or valves internwdiate of the hoppernml produerr, from thence to the gate or fiell opening into the producer itself. and from thence into the producer, in such a manner as to keep the producer scaled against loss of gas. l. accomplish lhr'se results through a single actuating element operating said doors, etc.

at. the proper lime and through the mechanism hereinal'tcr described.

Referring now to the drawings, 2 represents the. producer structure which is usually form and is provided at its upper portion with the usua receiving hop per 3 and havering hell 4 actuated through lever 5 pivoted at (3 and provided with a counterweight 7 Superimposed above the hopper 3 is supplernental receiving hopper 8 intermediate of the producer and the coal storage bin 9 provided with a series of opening and closin gates 10 mounted upon rock shafts 1.1 ant regular intervals.

provided at one side with a series of actuating arms 12. The hopper 9 is provided with a reduced discharge spout 13 adapted to discharge directly into hopper 8 and pro vided with opening and closing doors 14, 14, hinged at 15 and operated through pitmen 16 the terminals of which, preferably provided with rollers, engage the cam grooves 17, 18, of a vertically reciprocating cam 19 mounted by stem 20 in suitable guiding bearings.

The grooves 17, 18, of cam 19, shown in detail in Fig. 6, are oppositely sloped and preferably arranged on opposite sides so that when the cam is raised one of the pitmen 16 connected to one of the doors 14 will be forced in the opposite direction, opening the doors as shown in Figs. 2 and 5. On reverse movement of the cam and pitmen the doors will be reversed; closing them as in Fi". l.

The throat of spout 13 is preferably provided with means for varying its cross area so as to control the llow of the coal, for which purpose I employ adjustable gates 21 hinged in the sides of the spout at .22 and set inwardly to varying positions by means of adjusting lever 33 pivoted to one of shafts 22 and the connected lever mechanism by which both gates are simultaimonsly adjusted inwardly and outwardly. By this means the llow of the coal downwardly to the spout may be regulated so as to charge an approximately measured quantity thereiuto which is discharged by the gates l t at it will be also understood that the coal storage hopper may be dispensed with and the coal charged into hopper 8 in any other manner, as by shovels or barrows, so that said hopper is not necessarily included as an element of the invention.

It is desirable to open gates 14 and th lower the bell 4 during the closed period of the intermediate gates or valves 10, and to 0 en said gates 10 during the closed period of the gates 14 and hell 4, as indicated in Figs. 1 and 2 of the drawings, so that the llow' of coal to the producer is entirely out off during the lowerim of -the bell. For such purpose I preferably employ a single actuating element as shaft 24 from which through cams mounted thereon, the different motions are produced. For the purpose of raising cam 19, which falls by gravity, I

pro ide the cam 25 secured upon the shaft, a similar cam 26 being arranged to actuate valves 10 through arm 27 connected with the lever arms 12 .as clearly shown, said arm being connected with a lever 28 pivoted at .29, provided with a counterwei ht 3O tend 'ing at all times to throw said Wardly toward cam 26, a roller 31 or any lever outsuitable bearing portion being connected with said lever and arm, against which cam 26 null bear in its rotation.

The lever'5 of producer bell normally and extending outwardly from the side of cam 25. These different actuating mechanisms are so arranged and timed that they Will produce the opening and closing of the gates in the order stated, the operation being continuous and automatic.

It will be understood that'shaft 24 may be driven at suitable speed through anyconvenient form of gearing or driving me chanism, as indicated in Fig. 4, while the various motions and the times of their operation may be suitably regulated by the designing engineer.

The invention may be applied to any desired form of structure, or it may be changed or varied in different details by the skilled mechanic, but all such chan es or variations are to be considered as wit iin the scope of the following claims.

1V hat I claim.is:

1. The combination with a fuel-consuming structure having a hopper provided with a'lower emptying valve and upper receiving valves, of a superimposed vessel provided" with bottom-closing valves, and co-acting cam-d vices for operating all of said valves, substantially as set forth.

2. The combination with a fuel-consumin structure havin a ho per nrovided with h i .l.

a lower emptying valve and upper receiving valves, of a superimposed vessel provided with bottonnclosing valves, and co-acting cam--deviccs for opening said bottom-closing valves and lower emptying valve during the closed eriod of the receiving valves, substantially as set forth.

3. In a gas producer, the combination with a hopper having a charging bell, and superimposed receiving valves, of an upper charging hopper having a valve-controlled bottom, and co-acting cam-devices for openingand closing said bell, receiving valves, and valve-controlled bottom, whereby a charge of fuel may be successively delivered valves from said valves to the bell; and

from the bell to the interior of the producer,

substantially as set forth.
